This article dears with some problems related to application of Wolfgang’s and Ferracuti's subculture of violence theory explanation of violent criminal behaviour. Wolfgang and Ferracuti adopted in their concept cultural  approach to explanation of crime in general, and violent crime in  particular. Doing so, they rejected openly usefulness in this particular area of Merton’s anomie theory. They adopted so-called normative theory of culture, when means that they understand under the term culture a normative system consisting of values, norms and behavioral patterns, which exert pressure over individuals being under their influence, what results in uniformity of human behaviour. Application of this concept in criminology means that there may exist specific normative systems containing such values and norms which may lead individuals influenced by them to criminal behaviour. In other words it means, that when we observe within certain social group high criminality rates, higher than the average ones in a given society we may explain  them in terms of  the specific features of the culture of this group. This way of thinking is not totally new in American criminological literature. The best example of it constitutes W.B. Miller’s concept of flower-class culture as a generating milieu of gang delinquency. Wolfgang and Ferracuti claim that disproportionately high rates of violent crimes among and members of American lower-class (especially members of ethnic minorities) result from specific subculture existing within this social group, which they call subculture of violence. This subculture is the specific normative system which is characterized by tolerance and permissiveness which respect to the use of violence in interpersonal relations. The use of violence is  perceived by members of such subculture as something normal and natural, they do not consider it as either illegal or immoral. On the contrary, violent people showing physical prowess and readiness of high enjoy many social rewards, high social status and prestige. People who do not conform to the requirements of such subculture face many troubles within their groups, including even possible ostracism.             Wolfgang's and Ferracuti's concept contains evidently two separate layers. The first one, sociological, deals with subculture of violence as a social phenomenon and the problems related to the existence, functioning and transmission of violence related norms and values within society. The concept of subculture itself plays here a key role. The second one, psychological, deals with psychological consequences for the individuals of being under influence of such subcultural ethos. The main concern here are changes in attitudes and ways of perceiving environment resulting from the adoption of subcultural values, which one observes among violent people. These two layers are connected by very important thesis that aggression and violence constitute learned behaviour deeply internalised in the personalities of individuals. As it was said before subculture of violence thesis was conceived by Wolfgang and Ferracuti primarily to explain excessively high rates of violent crime among members of American lower class. But they point out as well to other examples of such subcultures as for example barbaricino code in Sardinia, customary vendetta in Albanova district in Italy, Colombian violencia or ,,criminal tribes'' in India. All  this means that they treat their concept as a broader integrated criminological theory of violent criminal behaviour not limited to specific American context.      One can point out to many attempts in the USA at empirical verification of the violent subculture thesis. First of all it is necessary to mention researches done by S. Ball-Rokeach and H. Erlanger. They attempted to verify Wolfgang's and Ferracuti's claims that there must exist significant differences in value systems and attitudes towards the use of violence between violent and non-violent persons, and that people who engage very often in violent incidents enjoy within their communities many social rewards including high status and prestige. The subculture of violence thesis was also used to explain a well-known in the American literature phenomenon of excessively high rates of violent crimes, especially homicides in the southern states. Among attempts at cultural explanations of this phenomenon one can point out first of all to contributions by Hackney, Gastill and Erlanger as well. All mentioned above researches hardly brought conclusive results. They involve many methodological shortcomings' and generally speaking seem to be too simply conceived, using too crude tools to pretend to be real tests of the subculture of violence thesis. This concept still awaits real, comprehensive attempt at empirical verification.             When evaluating Wolfgang's and Ferracuti's concept from the theoretical point of view one has to start from the proposition which seems - as it was said before-to constitute the core of the entire concept: aggression and violence constitute learned behaviour. At this moment it is easy to observe similarity with E. D. Sutherland's differential association theory. Sutherland was speaking about conflict between criminal and non-criminal cultures. Existence of this conflict made it possible for an individual to have contacts with patterns of both criminal and law-abiding behaviour.  Prevalence of one of them in the immediate environment of the individual decided about its future behavior. Very similarly Wolfgang and Ferracuti speak about the conflict between dominant culture (which they call non-violent culture) and subculture (which they call subculture of violence). This conflict makes possible differential association in the Sutherland’s meaning of the term. There is however one important difference. Sutherland, as it is well know, was strongly influenced in his thinking by G. H. Mead’s symbolic interactionism and sociology of Ch. H. Cooley, what resulted in particular attention paid to the primary social groups  and direct interaction. For Sutherland the process of learning criminal behaviour could take place only by means of direct interaction within primary social groups. It is not easy to interpret Wolfgang’s and Ferracuti’s theory with respect to this problem, as they are not very explicit within the subculture. It makes it necessary to  carry out a more detailed analysis of what they understand under the term subculture. They say on the one hand that the concept of subculture is strictly connected with the concept of social group. It seems however that this last concept they understand very broadly, when they say that individuals  sharing certain values, norms and behavioral patterns constitute social  groups. This means that under the term subculture they understand just individuals sharing particular norms and values, at least partly distinct from those existing in the dominant culture. This means as well that such sharing of values does not require direct interaction between individuals. It leads finally to a very important statement that subculture may exist widely dispersed spatially. It is necessary to underline that such understanding of the term subculture is not totally alien even to the contemporary adherents  of symbolic interactionism. An article by A. Fine and S. Kleinman constitutes clear example. The essence of this approach is an attempt to avoid ,,reification’’-as above authors call it-of the concept of subculture, what means equaling it with certain social structure, in other words social group. It seems however that one should not press this point of view to the extreme. Interpretation of the meaning of the term culture in terms of individuals behaviour is quite popular in social anthropology, to mention only R. Linton. But it may lead also to certain consequences absurd from sociological and behaviour point of view. It may mean that if somebody behaves in a certain way, he adheres to certain norms and values of which his behaviour is a result. If not, it means that he  does not adhere to them. In fact, it is a great simplification from the point of view of the mechanisms of human behaviour. In such a situation the concept of subculture lacks clear empirical meaning and loses its explaining potential. It seem  that Wolgang's and Ferracuti's stance results from a very individualistic approach paying attention only to the relation culture-individual, while neglecting a very important one: culture-social group.  Very helpful in solving presented above problems may be more detailed analysis of the psychological mechanisms of learning. What is interesting is that Wolfgang and Ferracuti do not go into details with respect to this, and mention only eventual usefulness of either Eysenck's or Bandura’s concepts. This lust one seems to be particularly suitable for the purposes of interpreting subculture of violence concept. Bandura's concepts of observational learning, as well as clear distinction between learning and performance, and analysis of the process of learning from three separate points of view, i.e. acquisition mechanisms instigation mechanism and maintenance mechanisms may be here particularly useful. It means that subculture of violence supplies to individual patterns of violence and aggression which are observed, memorized and in this way learned. It is also obvious that these patterns are not supplied by abstract subculture itself, but by behaviour of other individuals in the immediate environment. It is clear however that there are no people who behave constantly violently, what Wolfgang and Ferracuti admit, but do not elaborate on it. Learned violent patterns may result in violent behaviour only sometimes, when they meet necessary instigating stimuli. They may become more consistent and durable behavioral patterns only when necessary maintaining mechanisms come into being. It is obvious that subculture of violence may, serve as the supplier of both instigating and maintaining mechanisms. Especially these last may be very important. Bandura provides a very important distinction between internal and external control of human behaviour .Internal control means rewards, reinforcements coming from the individual's self. Here internalized values and norms come into action and play on important role. Behaviour, being in accordance with them brings satisfaction to the individual. This aspect of maintaining mechanisms constiutes main subject for Wolfgang and Ferracuti. But there is another one: external control, reinforcements, rewards coming from social environment, from social groups. Wolfgang and Ferracuti pay less attention or almost none to this aspect, because to analyse it one has to connect the meaning of the term subculture with the term social group, what they refuse to do. External control can not be an attribute of subculture itself. It is the function of groups. When one recognizes that subcultural system may be analysed only as a normative system of given- social groups, the possible influence of it becomes much broader. In such an interpretation subcultural influence is not limited only to mechanisms of internal control. Individuals may behave violently because they receive many external rewards for such behaviour. Because of this violent behaviour does not have necessarily to bring special satisfaction to the individual. Such behaviour may result from well known in social psychology mechanisms of group pressure and conformity with group standards.    In sum, it seems to be very profitable to use Bandura’s social learning theory to interpret and to broaden Wolfgang's and Ferracuti’s subculture of violence thesis. It is necesary of course to modify their use of the term subculture and connect it strictly with social structures and groups. In such a situation subcultural influence from the psychological point of view may not be limited to the mechanisms of internal control but extended to the external control by social groups, -what makes possible application of the theory as a theory of violent behaviour in general.

In 1975, two books dealing with female crime appeared. They aroused many controversies and polemics and inspired many empirical studies. They were Freda Adler's Sisters in Crime and Rita James Simon's Women and Crime. Both works attempted to explain the changes their authoresses believed were taking place in female crime with the influence of the women's lib movements. The two approaches, though similar in many points, show different patterns of connections between women's lib and female crime from which the latter's extent and direction of changes result.               F. Adler assumes that the women's lib movements of the 1960's and 1970's decidedly influenced changes in women's behaviour - the criminal behavior included. These changes resulted in an increase in the number and weight of offences committed by women. If such social movements continue –according to F. Adler - female crime will keep increasing and becoming similar to its male counterpart. Women will commit a greater number of the traditionally ,,masculine’’offences, i.e.offences against person, the more aggressive among offences against property, and the so-called ,,white-collar crimes’’ Contrary to  F. Adler, R. J. Simon focuses not on the ideology of women's lib but mainly on the increasing  professional activity of women which no doubt results largely from that movement. According to R. J. Simon, the women's increased professional activity will have twofold consequences: on the one hand women will get better opportunities to commit offences against property, and on the other hand, their greater material independence will lessen their frustration thus limiting the number of violent offences committed by women.                Empirical research aimed at explaining the trend and structure of female crime basing on F. Adler’s and R. J. Simon's conceptions tended in-two separate directions. In the first group of studies, the trend and structure of female crime were estimated. The other group included studies in which the interdependences were analysed between the changes that took place in the women's social status as a result of the women’s lib movement on the one hand, and the changes in female crime on the other han. Generally speaking, none of those studies aspired at verifying the whole of either F. Adler’s or R. J. Simon’s conception being limited  to verification of some theses only.                The present paper includes a discusson of studies carried out by D. J. Steffensmeier, M J. Hindenlang, V. D. Young, P. C. Giordano, S. Kerbel and S. Dudley, N. K. Wilson, J. G. Gory, and M. D .Lynes. Their findings were as follows.                No major changes could be observed in female crime after 1970. Instead, such changes had taken place in earlier years. What did change slightly after 1970 was the number of offences against property, and not all of them at that; namely an increase took place. The number of offences against the person was stable or showed a slight upward tendency which was, however, also found in the case of men. The grounds of liking women’s lib with female crime are questioned, as the latter changed prior to the rise of women’s movements. The notion of ,,women’s liberation’’ is not operational; moreover, professional activity is considered insufficient as the index basing on which to estimate the social changes which many have resulted from women’s lib. Female crime should be analysed in the context of the social changes that concerned women-to do it, however, appropriate indices of those changes ought to be chosen.                F. Adler’s and R.J. Simon’s conceptions still arouse many controversies today. The following objections can be raised to them: both authoresses estimated female crime basing on statistics of detentions by the police. As is well know, official statistics are the reflection not only crime itself but also of the functioning of administration of justice. Thus a single source is insufficient if the causes of changes in female crime are to be explained.                Two of F. Adler’s assumptions arouse certain doubts. The first of them is that women's lib included ail women and had a large effect on all of them: actually the movement only concerned the middle classes. Moreover, there is no evidence of the existence in American society of an actual social equality of men and women resulting from the equality of legally recognized chances. The other disputable assumption is that ,,masculinity" increases the likelihood of delinquency: it is uncertain whether and to what extent the social changes actually influenced women's different behaviour, and if they did, whether women really adopted masculine patterns of behaviour.                The conception of R. J. Simon, although more complete and better verified, includes a disputable contention that the increased professional activity of women lessens their frustration thus reducing the resulting violent offences. Admittedly, the new professional roles the women assume may improve their self-image and thus level stress; but on the other hand, the fact that they have to perform several social roles at the same time may give rise to frustration resulting from inability to perform all of those roles equally well. Therefore, if we follow this path of reasoning, the number of violent offences committed by women should remain stable as professional activity may influence the women's minds differently not only lessening but also deepening their frustration.                The discussion of female crime, taking place in literature, gave rise to the question whether and to what extent that phenomenon changed in Poland. Basing on court statistics, an analysis was carried out of the extent of female crime in the years 1946-1986 and of its structure in the years 1977-1986.                 The number of convictions of women and their proportion in the total number of convictions underwent significant changes over the forty years from 1946 till 1986. In the forties and the early fifties, the number of convictions of women went up rapidly at a rate greater than that of convictions of men. In the late fifties, that upwards tendency still persisted but was less marked than was the case with men. In the sixties, the number of convictions of women went down markedly, to remain stable with a slight upward tendency in the seventies. The legislative changes in penal law and the several amnesty acts in the eighties make an appraisal of the extent of crime in that period rather difficult. In the years l980-1983, there was a drop in the number of convictions of women, followed by an increase in the years 1984-1986 which no doubt resulted from the introduction of two acts: on education in sobriety and the fighting of alcoholism, and on the fighting of profiteering. If we consider the above-mentioned conceptions, that of R. J. Simon in particular, in relation to female crime in Poland, the years, 1946-1955 seem especially to confirm the hypothesis as to the connections between professional activity of women and female crime. In those years, a rapid increase of women's employment took place, and their social status changed greatly.                Female offences are mainly those against property. Convictions of women for such offences constitute over 70 per cent on the average of all convictions of women the respective percentage being over 50 in the case of men, while the average 11 pet cent of women are convicted for offences against the person (as compared to over 30 per cent of men).                The changes in female crime in Poland in the years 1977-1986 differ greatly from what F. Adler and R. J. Simon anticipated. There was a drop in the number of convictions for offences against property in the years l977-1984,while as regards offences against the persons, the number of convictions was stable or showed a slight upward tendency; there was an increase in the respective numbers in that same period as regards convictions of men. A rise in the number of convictions of women in the years 1984-1986 issued mainly from changes in penal legislation and from the resulting practice of prosecution.                As shown by the analysis of female crime in Poland based on court statistics, the available data were greatly insufficient to interpret the changes observed. Several different sources of information about crime ale necessary, as well as several standards or estimation (numbers of detected offences, of persons found guilty, of convictions).               Professional activity of women, the impact it has on their social situation, and its possible connections with the change in female crime, indicated by R. J. Simon, may also help explain that phenomenon in the Polish conditions but only together with many other factors which may influence the extent and structure of female crime.

The object of the paper is to show the trends of convictions for aggressive offences in Poland in the years 1972-1987 basing on court statistics, and to characterize this type of offences and their perpetrators. Moreover, basing on the findings of several Polish criminological studies, some of the factors have been indicated which may play an important part in the origin of aggressive offences. The main focus here is the problem of such offenders aggressiveness and their drinking habits, as the two factors are rather clearly connected with the discussed type of offences. Offences to be submitted to statistical analysis have been separated according to psychological and criminological criteria and not to the classification adopted in the Polish penal code. Thus only those offences from various chapters of the penal code have been taken into account where the facts of the given cases contained an explicit element of physical aggression against person or object, or of verbal aggression. Naturally, there is a great variety of acts which contain an element of aggression and are numbered among offences: they infringe different human values and interests from as vital as life and health to dignity, honour, or religious feelings. Also different is the seriousness of those acts (both misdemeanours and crimes being found among them), as well as the danger they create to the public weal, and the statutory penalties provided for them. Throughout the analysed period 1972–1987, the total number of convicted persons was relatively stable and amounted to the average of 150–160 thousand a year; it went down in 1977 and 1981–1984, only to increase again to the previous level in the years 1985–1987. Also the crime rate fluctuated similarly, amounting to 65–59 per 10,000, adult population, with the exception of 70.6 in 1972. In some years, the decrease of both the number of convictions and the crime rate can be explained with amnesty laws, while the increased number of convictions, in the years 1985–1987 resulted, among other things, from certain additional though temporary legal regulations introduced in that period (particularly from the Act  of 1985 on special criminal responsibility). In the period under analysis, the proportion of persons convicted for aggressive offences amounted to about 40 per cent of the total number of convictions. At the same time, starting from 1975, a certain slight downward trend in the proportion of such convictions can be found, to as low as 35-36 per cent in the years 1979–1980, followed by an increase to the previous level. A certain decrease in the extent of convictions for aggressive offences can be explained partly with demographic changes. In the period under analysis, despite the general increase of the population aged 17 and more (by 12.9 per cent),  the number of men aged 17–20 went down by about 35.5 per cent, and the same trend could be found in the case of men aged 21–24. It is a well-known fact that aggressive offences are committed mostly by young persons. Analysing the extent of aggressive offences from the point of view of the offenders’ sex and age, we find somewhat different trends in young adult as compared with adult men and women. Aggressive offences constitute about 60 per cent of all offences committed by young adult men, and 34–40 per cent of those of adult men. In the period under analysis, offences of this type committed by young adult men kept up the above level, fluctuations being greater in the case of adult men. In the structure of female crime, aggressive offences play a less significant role and constitute about 20 per cent in both age groups. There is also, as in the case of men, a distinct trend: stability of proportion of convictions of young adult women for such offences (about 20 per cent), and a distinct decrease in the case of adult women (from 23 to 12.6 per cent). Taking certain groups of offences as well as the separate acts into account, we find a considerable increase in the number of aggressive offences against property. It is determined mainly by the increase in the proportion of convictions for burglary and of particularly audacious larceny, and to a slight extent – for damage to property. Instead, proportions of convictions for robbery are rather stable. In the discussed period, robbery which contains an explicit element of aggression revealed no changes as regards the number of convictions: instead, upward trends could be found mainly in the case of burglary and of particularly audacious larceny where explicit aggressive traits can not always be found. Thus this finding corresponds but to some extent with the world trend. In the discussed period, a downward trend could be found as regards convictions for offences which involved physical and verbal aggression against person. Convictions for offences traditionally regarded as serious and dangerous for the public weal, such as murder or rape, remained at the same level, while those for bodily injury trended downwards. As has been mentioned above, the number of robberies, also included among serious offences, remained stable, the proportion of convictions for offences of this type arnong all convictions for aggressive acts being rathen low (murder, 0.5–07 per cent; rape, 2 per cent; robbery, 6.8 per cent). What should also be stressed is the decrease in convictions for participation in a brawl or battery, particularly in rural districts, and for assault on a public functionary or police officer, starting from 1978. Instead, convictions for physical or moral cruelty towards a family member maintain a rather high level with a slight upward trend. A regular increase it the number of convictions for that offence which dates from 1950s, is related to the trends in prosecuting and sentencing policy in family cases. The influence of the changes in criminal policy and legislation is also distinct in the case of convictions for violation of bodily inviolability, insult, and insult of a police officer which went down to begin with and then started increasing in numbers. The second part of the paper contains a discussion of the problem of conditions of aggressive crime. An attempt was made basing on the findings of criminological studies to answer the question whether most perpetrators of aggressive offences can be characterized as highly aggressive persons and excessive drinkers. The analysis concerned both the fact of repeated perpetration of aggressive offences, and the occurrence of aggressiveness as a permanent personality trait. As may be concluded from the studies of offences committed by different samples of young adults those in whose criminal career was at least one aggressive offence (c.g.) robbery, hooligan act, homicide) were more frequently than others convicted for aggressive offences. Thus the question should be answered whether most of the perpetrators of aggressive acts are characterized by distinct aggressiveness as a permanent personality trait. One can hardly suppose in this connection that a single aggressive offence might constitute a sufficient proof of the offendner’s aggressiveness. If, however one and the same person repeatedly commits aggressive offences, he might be an aggressive individual. A person has been defined as aggressive who reveals aggressive behaviour or a decidedly hostile attitude towards many persons in different situations. It has been found basing on psychological examination with the Buss- Durkee questionnaire and detailed data from interviews (which the authoress used to construct scales of aggressiveness), that most perpetrators of aggressive offences are characterized by a considerable aggressiveness as a relatively stable personality trait. Moreover, aggressiveness measured this way is a significantly less frequent characteristic of young adult offenders against property, and of non-delinquent youth. The above findings contribute but to some extent to the explanation of the nature of aggressive crime, as aggressiveness of offenders should be considered in connection with many other factors which exert a mutual influence on one another and jointly determine a criminal act in a given situation. In studies of various samples of aggressive offenders, their considerable excessive drinking was found. The issues under analysis included, among other things, the role of drinking in the origin of aggressive crime, alcohol’s direct as well as indirect influence on criminal behaviour taken into account. It was arqued that the offender’s intoxication plays a greater part in the origin of aggressive crime than of offences against property. Also the interdependence between aggressiveness and excessive drinking. As shown by the findings (among other things, of studies of young adult perpetrators or robbery and hooligan acts), excessive drinkers revealed intense aggressive behaviour significantly more often than those who did not drink excessively; moreover, such behaviour was found already at school which means that those persons were already aggressive as children, before they developed excessive drinking habits. Theorefore, their subsequent regular drinking could have been related to emotional instability with which also their aggressiveness was connected. They could have seeked relief of their emotional tension in excessive drinking. Also aggressive behaviour served to abreact that tension. To conclude, it should be stated that the perpetrators of aggressive acts, as opposed to those who commit mostly offences against property, are highly aggressive as a rule. Most of them also regularly drink excessively. Though they were not found to be significantly different in this respect from offenders on the whole, nevertheless alcohol no doubt plays an important part in most of their aggressive acts. In a given situation, their excessive drinking habits, intoxication at the moment of the act, or aggressiveness caused or intensified their already existing serious conflicts with the environment, influenced their distorted perception and interpretation of the reality, and facilitated an impulsive reaction to casual misunderstandings, and could therefore contribute to the emergence of aggressive acts qualified as offences.

Opis:
The article presents results of a research conducted for the Ministry of National Education and Sports, which primarily aimed to look closer at the  changes in forms, scale and increase of aggressive behaviours of students at all the different learning and upbringing stages. The first kind of such research in Poland was initiated by K. Ostrowska and A. Siemaszko in 1981. Its results were widely discussed by A. Siemaszko in his book „Deviated teenage behaviours”. Next research, which is a direct source of reference for the research discussed in this article, was a countrywide research into aggressive behaviours of students, conducted in 1997 also from the initiative of K. Ostrowska, with a cooperation and extensive financial involvement of prof. Hans Ludwig Schmidt, dr. Janusz Surzykiewicz and the Bosch Foundation. Similarly as in the past, the results were thoroughly presented in a monography „Aggression and School Violence. Socio-economic conditions” written by Janusz Surzykiewicz. The presented research concerning aggressive behaviours of students in 2003, is based on answers of respondents about causing and experiencing aggression across a 12 months period before conducting the research. Questionnaires in self-report technique were conducted in November and December 2003. A group of 16 students was randomly sampled from ministerial lists of primary, lower secondary, general secondary schools, specialised secondary schools, technical secondary schools as well as basic vocational schools. Research has been conducted in all 16 provinces of Poland. In the randomly sampled schools a suitable number of students was randomly sampled from each teaching level. In relation to 1997 the number of surveyed students is smaller, the previous counted 2567 individuals. Contraction of this group was dictated by financial and time limitations of the research. This article includes characteristics of student respondents by their age, kind of school, class, place of living, family situation including family structure, marital status of parents, current residing or other persons, with parents, age of parents, their education and professional activity. The socio-demographic characteristic of the families indicated that in 90% of cases students come from complete families, they have parents, in the age of professional activity (35-50 years of age) with vocational, secondary and higher education. However, there is a worrying fact that about 20% of families is struggling economically due to the lack of permanent employment. The characteristic of aggressive student behaviour concerns, on the one hand, a number and percentage frequency structure of 41 behaviours considered in the research as an indicator of aggression, on the other hand - an analysis according to the differentiated categories of aggression. These are behaviours which have a smaller potential effect – they would cause a considerably smaller, danger, pain, harm, suffering i.e. spreading lies about other students; and ones which could be called examples of serious aggression or even as bearing characteristics of criminal offences such as: threatening with a knife, a razor blade, gas or using a sharp object while in a fight. The most common signs of aggression on the school area the less potentially harmful behaviours, they create a specific school atmosphere. Amongst those to mention would be: cheating on teachers, disrupting teaching in class, offensive talking, calling other students names, writing on school walls and desks, purposeful pushing others, spreading lies and harming oneself by drunkenness. Such forms of behaviour happen to 30 - 40% of respondents. However, as it has been mentioned in detailed descriptions, school is also a place where more serious forms of aggression take prace. These are: forcing students to do things against their will, fighting with other colleagues, group beating of a single student, forcing or provoking sexual behaviouts, using sharp objects in a fight. The article incorporates data suggesting an increase in aggressive behaviour amongst girls, and the still remaining statistically significant  differences between girls and boys especially in the growth of aggression and in  some more serious forms of aggression. Furthermore, a characteristic of aggressive student behaviours is presented taking into account six. categories: aggression and physical abuse, aggression and verbal abuse, psychological abuse, aggression and violence with objects, aggression and violence using gun, sexual abuse, and all other kinds of demoralisation and social maladjustment. A comparison of referenced findings from 2003 with those from 1997, required using not only the same research procedure (self-report questionnaire) but also taking up the very same classification of aggressive behaviours. Prevention of aggressive student behaviours can be effective if performed after correct diagnosis of such phenomenon, of its causes and only if an adequate means to diagnose will be used. An important element of the diagnosis is recognising aggression amongst students depending on the stage of their primary and secondary education. In 1997 there was no early secondary schooling yet, therefore only primary and secondary school students were verified. This very article introduces results of strengthening of different forms of aggressive behaviours in primary, lower secondary, general secondary schools, specialised secondary schools, technical secondary schools and basic vocational schools. What can be quickly noticed is a fact that all named forms of violent behaviours take place in the studied population independently of the kind of school, yet their intensity is different. These differences are provided by the received chi-squared coefficients presented in the tables. An additionally modified categorisation of aggression has been used for a more clear and efficient presentation of aggressive behaviours in schools for the future prevention. Two criteria have been taken -  the strength of a deed and who it is directed at. In that way nine, instead of six, categories of aggression have been established: aggression and physical abuse, aggression against teachers, aggression against objects, psychological abuse, auto-aggression, family disobedience, verbal aggression, aggression with threatening to use a dangerous object, sexual abuse, take over, theft, being arrested by the police. For primary school the most characteristic behaviours are verbal aggression (31,1% of students admit to behave that way), physical aggression but to a lesser  degree (13,7% of students), aggression against teachers (11,6%) aggression against objects (8,8%). Other forms of aggression occur less often, they are admitted by 2,6% to 5,1 % of students. In the lower secondary schools we can  observe a higher figure of students using also other forms of aggression. Still the dominant form of aggression is the verbal one (38,1% of students), auto-aggression appears more strongly in form of alcohol and abuse of  other psychoactive substances (19,9%), aggression against teacher has a higher level too (19%), as well as against objects (17,2%), physical abuse (12,7%). Psychological abuse, together with family disobedience occur more often than in primary schools. There is another difference in escalation of aggressive behaviours at the stage of lower secondary schools. Secondary schools, specialised secondary shools, as well as basic vocational schools, as shown in the forms of diagrams, indicate similar symptoms of aggression, the strength of such behaviours is also comparable within that group. The most common are: auto-aggression, verbal aggression, aggression against, teachers, aggression aguinst, objects, physical abuse, family disobedience, thefts, psychological abuse. Students in basic vocational schools differ in kinds and strength of aggressive behaviours. And primarily, more commonly than other students in their age, they show aggression and physical abuse. Diagnosis of aggression should not only focus on the knowledge about the offenders but also on the knowledge about the victims. This aspect has thus been discussed in this research. Twenty nine incidents of aggression have been analysed, victims of which could have been students. The aggressors could have been their colleagues, teachers, or other people. This side of a problem is not mentioned in the article. What has been under study, however, was the correlation between being an aggressor and being a victim, as well as on finding out the so-called ‘only aggressors’ and ‘only victims’. The research has confirmed the dependency between being a victim and being an aggressor. Factor analysis enabled for a differentiation of the types of ‘only aggressors’, five factors were found, and types of ‘only victims’ – seven factor found, and mixed types, ‘aggressors and victims’ - five factors. The aggression diagnosis amongst students based on the analysis of kinds of forms, their intensity and popularity within a population, is at the end of the article and it allows for stating that aggressive student behaviours are becoming a particular form of student ‘adaptation’ to the expectations of other fellow students, teachers and parents. They take more diversified forms, the number of behaviours dangerous to health and safety increases, too. Students attack teachers more often, despite the fact that teachers do try to limit their aggressive behaviours. In the student environment there is a growing number of far more serious incidents. The higher the education stage, aggressive behaviours do not decrease, the numer of aggressive students increases and the hierarchy of their order changes. The most worrying is an increase in number of students abusing alcohol and other psychoactive substances. Such behaviours are considered as forms of auto-aggression in this article. The report finishes with conclusions addressed to teachers, pedagogues, and pedagogic school supervisors for they could be included in the educational programmes and prevention methods to which schools are obliged by the adequate legal acts from the educational system and ministerial directives.

Opis:
Problem utrzymania oraz należytego wykonania obiektów betonowych i żelbetowych jest w ostatnich latach bardzo istotnym argumentem prowadzącym do tworzenia coraz to nowych, lepszych materiałów. Zagadnienia odpowiedniej ochrony budowli przed ciekłymi środowiskami agresywnymi i czynnikami atmosferycznymi są na tyle istotne, że poświęca się im coraz więcej miejsca w różnego rodzaju publikacjach. Uszkodzenia betonu najczęściej są spowodowane: 1.oddziaływaniem chemicznym (głównie kwasów - soli odladzających, a także chlorków), 2.oddziaływaniem mechanicznym, 3. szkody spowodowane cyklicznym zamrażaniem i rozmrażaniem.
This paper presents the results of the investigations of concrete on the basis of various cements available on the building market and subject to the influence of various aggressive environments (chloride, sulfate and ammonium). Considering a wide scale of the issue, attention was paid to basic tests (compression and bending) of samples after 28, 60, 90 and 180 days of their stay in an aggressive environment. The tests demonstrated that the phase composition of cements, and especially of the main components (alite, belite, celite and brownmillerite) have a fundamental influence on the durability of concrete exposed to any aggression. The images of the microstructure show differences in the created post-hydration forms and suggest the influence of aggressive environments on the cement stone set. Small quantities of calcium hydroxide and Friedel's salt have an advantageous influence on the effectiveness of the protection of concrete by a significant concentration of the microstructure and smaller pores in the material. As consequence, the possibility is limited for aggressive ions to penetrate deeper parts of the materials, which results in its better protection. Another conclusion from the investigations carried out is the greatest versatility of the application of CEM III/A 42,5 HSR/NA metallurgical cement, whose application with a low content of lime tri-carbonate silicate on the level of 29.29 per cent and a relatively large content of lime tri-carbonate aluminate (4.67%) gives statistically the best results in the form of concrete protection from among all the cements tested.

Trwałość konstrukcji inżynierskich z betonów cementowych o wysokich wytrzymałościach stanowi dzisiaj bardzo ważne zagadnienie w aspekcie ich niezawodności w określonych klasach agresywnego środowiska oraz przy obciążeniach dynamicznych. Autorzy uważają, że powyższe zagadnienie może być rozwiązane poprzez zastosowanie metod chemiczno-mechanicznych zapewniających właściwą ochronę materiałowo-strukturalną konstrukcji w określonych warunkach użytkowania. Do chemicznej modyfikacji mikrostruktury betonu stosowano w badaniach pastę asfaltową w wysokowrzącym rozpuszczalniku, zaś do formowania struktury betonów specjalne metody zagęszczania mieszanki betonowej.
The durability of engineering structures with cement high performance concrete nowadays is the very important issue in the aspect of their reliability in determined classes of the aggressive environment and at dynamic load. In authors opinion the above issue can be solved by applying chemical-mechanical methods ensuring the proper material-structural protection in determined conditions of the use. For the chemical modification of microstructure of concrete asphalt paste, dissolved in high boiling organic solvent, was applied, whereas for forming the structure of concrete special methods of consolidation of concrete mixture was used.

Opis:
Canine mammary sarcomas are usually very aggressive and easily metastasize. Unfortunately the biology of this type of tumor is not well known because they are a very rare type of tumors. The aim of this study was to find differences in gene expression patterns in canine mammary osteosarcomas (malignant) versus osteomas (benign) using DNA microarrays. Our microarray experiment showed that 11 genes were up-regulated in osteosarcoma in comparison to osteoma whereas 36 genes were down-regulated. Among the up-regulated genes were: PDK1, EXT1, and EIF4H which are involved in AKT/PI3K and GLI/Hedgehog pathways. These genes play an important role in cell biology (cancer cell proliferation) and may be essential in osteosarcoma formation and development. Analyzing the down-regulated genes, the most interesting seemed to be HSPB8 and SEPP1. HSPB8 is a small heat shock protein that plays an important role in cell cycle regulation, apoptosis, and breast carcinogenesis. Also SEPP1 may play a role in carcinogenesis, as its down-regulation may induce oxidative stress possibly resulting in carcinogenesis. The preliminary results of the present study indicate that the up-regulation of three genes EXT1, EIF4H, and PDK1 may play an essential role in osteosarcoma formation, development and proliferation. In our opinion the cross-talk between GLI/Hedgehog and PI3K/AKT pathways may be a key factor to increase tumor proliferation and malignancy.

Introduction: Year by year the level of suicide attempts among the young people increases systematically and the age at which adolescents attempt suicide decreases. Among the factors connected with suicidal behaviour, literature mentions aggressive behaviour and attitudes. Aim: The aim of the study was specification of the level of aggression, its intensity and the way of expressing it in the group of young persons after suicide attempts. Material and method: The group of subjects after suicide attempts included 99 persons and they were compared with the control group of 301 persons. We used the Psychological Inventory of Aggression Syndrome (IPSA) and the Anger Expression Scale (SEG). Results: The results of the study showed that adolescents after suicide attempts exhibited an increased level of aggression and anger, they found it difficult to manifest in a socially acceptable way the attitudes and behaviours recognized as aggressive; they were characterized by the lack of the capability to express anger or other negative emotions, less often made negative self-estimation, rarely manifested hostile desires in relation to other people and exhibited few seemingly non aggressive behaviours. Moreover, such adolescents rarely transfer their aggression on inanimate objects, they are less noisy, quarrelsome and vulgar, they less often undertake activities recognized as physical violence. Conclusions: The above results may be used to construct strategies, programmes and support groups for adolescents with suicidal tendencies.
Wprowadzenie: Z roku na rok systematycznie wzrasta liczba zamachów samobójczych wśród młodzieży, a także się próg wiekowy adolescentów podejmujących próby samobójcze. Wśród czynników wykazujących związek z samobójczością w grupie nastolatków literatura przedmiotu wymienia zachowania i postawy agresywne. Cel: Celem niniejszej pracy było określenie poziomu agresji, jej nasilenia, sposobu ekspresji w grupie młodych osób po próbach samobójczych. Materiał i metoda: Grupa badanych po próbie samobójczej obejmowała 99 osób, porównywano ją z 301-osobową grupą kontrolną. W pracy wykorzystano Inwentarz Psychologicznego Syndromu Agresji (IPSA) oraz Skalę Ekspresji Gniewu (SEG). Wyniki: W pracy stwierdzono, że młodzież po próbach samobójczych wyróżnia się podwyższonym poziomem agresji oraz gniewu, trudniej manifestuje w sposób akceptowany społecznie postawy i zachowania uznane jako agresywne, cechuje się wyraźnym brakiem umiejętności wyrażania złości, gniewu lub innych negatywnych emocji, rzadziej dokonuje negatywnej samooceny, rzadziej przejawia wrogie pragnienia wobec innych ludzi i stosuje mało zachowań pozornie nieagresywnych. Ponadto rzadziej przenosi agresję na przedmioty martwe, jest mniej wrzaskliwa, kłótliwa i wulgarna, rzadziej podejmuje działania noszące znamiona przemocy fizycznej. Wnioski: Niniejsze wyniki mogą być wykorzystywane do konstruowania strategii, programów i grup wsparcia dla młodzieży ze skłonnościami suicydalnymi.

Opis:
The study presents results of research conducted by means of the BPAQ and Cyber-Bullying Tolerance questionnaires on a sample of 788 elementary school pupils of the 8th and 9th grades. It shows an increase in verbal aggression, hostility and anger in the pupils. In terms of gender, the increase was confirmed in verbal aggression in boys and physical aggression in girls. Tolerance to cyber-bullying as a form of aggressive behaviour increases with the development of science and technology and the increase in pupils´ aggressive behaviour. Knowledge of manifestations and causes of pupils´ aggressive behaviour is the basis for the educational work of teachers and other professionals.

Opis:
Zachowania agresywne zaczynają być codziennością życia szkoły, z czym ani rodzina, ani sama szkoła nie umie sobie poradzić. Jeżeli chodzi o przyczyny środowiskowe, to źródeł takich zachowań należy szukać u rodziców i nauczycieli. Proces wychowawczy ma różne style, stąd i różne późniejsze zachowania dzieci. Wpływ rówieśników, przyjaźnie, społeczne nastawienia – mogą albo tonować niektóre zachowania, albo prowokować do rozwoju agresji (np. naśladownictwo w zachowaniach). W swoim artykule starałem się przeanalizować zachowania, zwłaszcza rodziny i szkoły, które to poparte zostały badaniami przyszłych nauczycieli, gdzie konkluzje mogą zaskakiwać, ale i skłaniać do refleksji.
Aggressive behaviours begin to be a commonplaceness of the life of the school, with which neither family nor the school itself can cope. In relation to environmental causes, one should look for sources of such behaviours in parents and teachers. The educational process has various styles which leads to children’s various later behaviours. Peers’ influence, friends, social attitudes – they can either tone down some behaviours, or provoke a development of aggression (e.g. mitation of behaviours). I tried to analyse behaviours in my article, especially the family and the school, which are supported by the research of future teachers, and the conclusions can be surprising, but they induce reflections.
